This is a white paper on horns formed when cutting lacquer discs. I made this available in 2011 and making it available again for those new to lacquer cutting since then.

It was written by the now defunct Keysor-Century Corporation, USA who were well known for their PVC vinyl compounds and their disc cutting studios, K-Disc in Los Angeles. It explains the causes of horns, their effect on plating and the finished vinyl pressing. It also offers some suggestions on how to avoid them.
